10/100Baset And 10/100/1000Baset Connectors - Cisco IPS-4255-K9 - Intrusion Protection Sys 4255 Installation Manual

Cable Pinouts

10/100BaseT and 10/100/1000BaseT Connectors

Sensors support 10/100/1000BaseT ports. You must use at least a Category 5 cable for
100/1000Base-TX operations. You can use a Category 3 cable for 10Base-TX operations.
Note Some sensors support 10/100BaseT (IDS-4210, IDS-4215, and the optional 4FE card) while others
support 10/100/1000BaseT (IDS-4235, IDS-4250-TX, IPS 4240, and IPS 4255). This only applies to the
copper appliances. The fiber appliances support 1000Base-SX only.
The 10/100/1000BaseT ports use standard RJ-45 connectors and support MDI and MDI-X connectors.
Ethernet ports normally use MDI connectors and Ethernet ports on a hub normally use MDI-X connectors.
An Ethernet straight-through cable is used to connect an MDI to an MDI-X port. A cross-over cable is used
to connect an MDI to an MDI port, or an MDI-X to an MDI-X port.
